VOLUME-MEASURING APPAEATUS FDR LIQUIDS.

Application filed January 29 Our invention relates to the installationof fixtures and lind specilic application in the installation ofgasoline-dispensing apparatus. it consists in apparatus so organ izedand arranged that inaccessible, parts may in installation be broughtprecisely to accurate position.

In the accompanying drawings Fig. l is a view in elevation of agasoline-dispensing fixture, of the general character now commonly to befound at filling stations along automobile higlnvays; Fig. H is a viewto larger scale, showing fragmentarily and in plan a detail of thefixture shown in Fig. I.

The i'liitlll'Q shown in elevation in Fig. 1 includes a hollow pedestall of cast iron, and an elevated measuring chamber 2 of glass. Themeasuring chamber is cylindrical and stands in vertical position; it isalternately filled and emptied as the appara tus is used; and it isformed of glass that the purchaser may see his desired volume ofgasoline, first segregated within it, and then drawn from it to the tankof his car. This measuring chamber is necessarily remote, being raisedhigh on its pedestal 1; its bottom wall in the particular fixtureillustrated is seven feet above the ground. And such elevation isnecessary, in order to effect delivery by gravity to the tanks of carselevated at various distances from the ground. A conduit is providedwithin the hollow base through which gasoline is drawn from a source ofsupply to the measuring chambenand a flexible hose 3 is provided,tl'irough which a quantity of gasoline segregated in the measuringchamber may be drawn off and delivered to the tank of'awaitingautomobile. Within the measuring chamber 2 means are arranged whereby,in accurate response to the shifting of a hand lever l, a preciselydetermined quantity of gasoline drawn from the source of supply may becarried to and retained in chamber 2 preparatory to delivery to acustomer. The particular structure and method of operation of thisapparatus for segregating within measuring chamber 2 a predetermined'volume of gasoline, does not now concern Each instrument after it hasbeen built and before it leaves the factory is very carefully calibratedand adjusted, to the end that it shall deliver, as required, preciselyone,

he had the knowled e, to make his installation with careful accuracy inthe position of the iixture. It is not a dniicult matter within the shopand with shop arrangements to bring the measuring chamber to positionwith the bottom wall extending in accurately determined horizontalposition. All that is needed is a level, and from the staging which inthe shop is provided, it is a simple matter to read a level andto makeadjustment. But under conditions of installation the .measuring chamberis remote, elevated above the level of the eye, and the leveling of themeasuring chamber then becomes a matter of difficulty; the necessity ofaccurate placement may be unrecognized, and even if recognized, is sofar neglected or ignored that a rough approximation to correct positionis got and nomore. The one who makes v the installation goes so far, andlets it go at that.

In the practice of our invention we pro-' vide at a convenient and lessremote place on the pedestal, and at such height as to be at the time ofinstallation fairly in the field of observation, level seats. In theapparatus shown in Fig. I a ledge 5 will be seen, formed intermediatethe height of the pedestal 1.. On this ledge 5 we provide a boss (3 withextended surface-which when installation is made will lie inapproximately horizontal plane. In this surface the level seats alludedto are formed. Ordinarily there will be two level seats 7 and 8. Theyconsist of elo-ngate grooves, they extend angularly one to the other,and conveniently they are connect- And, as should have been said above,and

as will now be realized, the fixture is at this time an assembledentity, securely bolted part to part, and moves only as an entity.Leveling then is effected by adjusting the jacks or other support uponwhich the fixture stands. Calibration is elt'ected upon the so leveledinstrument. Then leveling has so been efiected, two levels set in theseats 7 and 8 are adjusted untilvthey both read level, and they then aresecured in such positions. These levels will ordinarily consist of thefamiliar gla 2; tubes incompletely filled With liquid, and they aresecured in their seats by being sunlt in a plastic and rapidlyhardening'inatrix, such as litharge ground in oil to a paste. lVhen theyhave been accurately placed and when the litharge matrices havehardened, the levels will remain in miovable. r i

The instrument calibrated and provided with levels set in the mannerdcscribed is so far ready for installation that when it is set up inposition for servic the levels in seats 7 and 8 are immediately undcrtheeye; the instrument may then be set up in position for service, and maybe adjusted in its n'linute position; leveling may thenlle readilyandaccurately effected; and when the levels 7 and 8 read true theinstrument may be made secure. The desired end then is gained: themeasuring chamber above sandstrue, as when calibrated, and suchinaccuracy in measurement as We hitherto have found in earlierinstallations to be dueto in accuracy invplacement, avoided andcorrected. 1 i

We claim as our invention:

'1. r-Lfixture supporting rigidly a remote voltune-measuring chamberand, less remote ly, and rigidly with respect to said chainher, a level.the said level being in its positien coordinated to the Walls of themeasur 111g chamber.

2. A rigid fixture for the dispensing of gasoline supporting an elevatedmeasuring chamber with bottom wall extending in, a

plane and having tivo levels mounted thereon le elevation than and infired position "anged angularly one to another both'ot said levelsarranged in coordinated posltlons with the bottom mu of the measuringchamber. V
